Kev - I often think the same. Actually, I think what happens is that various items are donated to small theatre companies -
whilst the big Companies buy up all the old uniforms they can from military and police sources. Perhaps at some time they
may require additional ones and then commission - but, still using what they have in stock. This could account for the badge.
I don't suppose we will ever know - however, I would advise that you get on-the-spot advise on the badge. See if a military
auctioneer thinks it has a value as it is - and, if re-enamelling would add to value ? Mervyn
